To endure is to forgive
Finally, "love endures all things."... Everything that is tough and brittle shatters; everything that is cynical rots. The only way to endure is to forgive, over and over, to give back that openness and possibility for new beginning which is the very essence of love itself. And in such a way love comes full circle and can fully "sustain and make fruitful," and the cycle begins again, at a deeper place.
